Just in case you don't know, Thai people will refer to ourselves as ผม (male) or ดิฉัน (female) only in really formal situations. When you become someone's friend or know them better, you can refer to yourself by your own name.

For example, my name is Notti. I refer to myself as "Nott" น็อตเป็นคนไทย น็อตเรียนภาษาญี่ปุ่นอยู่

But, if our names are quite long, like ยุวดี, we will shorten the name to just ยุ.For example, ยุเป็นคนไต้หวัน ยุเรียนภาษาไทยอยู่
